Abstract

<P>La présente invention concerne un dispositif d'éclairement et de captation ainsi qu'une méthode pour l'analyse de fluorescence, où l'éclairement d'un courant de particules produit de la lumière fluorescente. <P> This invention relates to an illumination and capturing device and a method for fluorescence analysis, where the illumination of a product stream of particles of the fluorescent light. </P><P>Selon l'invention, un réflecteur 12, ayant une surface concave 14 avec un premier foyer 16 disposé dans le courant des particules, réfléchit un rayonnement d'éclairement organisé, ce rayonnement convergeant sur le premier foyer 16 pour stimuler les particules pour qu'elles produisent la lumière fluorescente; </ P> <P> According to the invention, a reflector 12 having a concave surface 14 with a first focus 16 disposed in the stream of particles, reflects an organized illumination radiation, this radiation converging on the first focal point 16 to stimulate particles to produce fluorescent light; la lumière fluorescente émane du premier foyer 16, dont une partie est réfléchie par la surface 14; the fluorescent light emanating from the first focal point 16, part of which is reflected by the surface 14; cette lumière fluorescente qui est focalisée sur le second foyer 18 ne contient pas de rayonnement d'éclairement et est recueillie pour une détection et un traitement subséquents. this fluorescent light that is focused on the second focal point 18 contains no illumination radiation and is collected for detection and subsequent treatment. </P><P>L'invention s'applique notamment à la détection des particules.</P> </ P> <P> The invention is particularly applicable to the detection of particles. </ P>
